System and method for improving reading-writing mode of ISO-18000-7 international standard label

Abstract

The invention provides a method for defining a signal having a required radio frequency characteristic into an instruction signal requiring a label to execute certain or a certain group of pre-determined operation by using the radio frequency characteristic, different from the radio frequency characteristics of other wireless signals, of a wireless data signal and a characteristic that quick identification can be performed through a radio frequency transceiver, and using a working frequency channel of a jump label simultaneously in order to solve the problem that a reader-writer represented by the international standardization organization (ISO)-18000-7 international standard wastes time and power during reading and writing of data on the label, so the problem that the battery life of the wireless communication equipment which is represented by an active electronic label and has low power consumption requirement is short can be solved basically. In the combination of a fixed time slot distribution mode, the speed and the efficiency of reading and writing the label on the basis of the ISO-18000-7 standard are greatly improved. Although the ISO-18000-7 defines an electronic label system having a 433M frequency band, the method can be applicable to any other wireless communication frequency bands and wireless communication systems.

Description

technical field [0001] The invention relates to the international standard of the active electronic label, in particular to the whole information reading and writing process of the label in the ISO-18000-7 standard. Background technique [0002] ISO-18000-7 (hereinafter referred to as the standard) is a well-recognized mature and widely influential 433M active electronic tag international standard, and has been used in the US military. The various methods adopted therein, especially the most important link-the method of reading and writing label information, are all subject to people's great attention, and engineers are also constantly striving to improve it, and the present invention is such an effort . [0003] In the standard, the reading and writing process of the system to the tag information is carried out as follows: for the purpose of power saving, the tag is usually in a periodic sleep controlled by the internal clock, and the wake-up signal is monitored for a mome...
